Catherine was just starting to doze off when she heard a quiet buzz from her phone. She groaned and considered ignoring it, but she hadn't heard from Lindsay in over a week and was hoping that maybe she had finally texted. Instead, she was surprised to see that the message was from Nick. It wasn't unusual for him to email her, or even call occasionally to chat, but she honestly couldn't remember the last time he had sent her a text. She was awake in an instant and punched the tiny phone icon next to his name.

"Hello? Catherine?" he answered, sounding every bit as drained and exhausted as he felt.

"Got your text. What's wrong?" Catherine asked, straight to the point. Nick was relieved that she didn't waste time.

"It's Sara." He said with a sigh as he rubbed his face and leaned against the car. "She didn't come in for work. We found her about an hour ago. She was unconscious. She's at the hospital now, Brass is with her." His voice broke as he took a moment to breathe. "We, uh, we don't know anything. I'm at her place looking for anything that might tell us what happened."

"Was she attacked?" Catherine interrupted, feeling her head swim. "Any sign of forced entry? Had she had any problems at work?"

"No, it wasn't suspicious. Nothing was out of place, no sign of forced entry. She just... she looked like she was asleep. Hell, when I found her I just thought she had slept through her alarm. But she didn't wake up, and even when I shook her she didn't respond... I thought" but she cut him off once again.

"Oh God, what about Gil, someone has to call him! Where is he, even? Is he on his way back? Was he there?" her words raced ahead of her thoughts.

"Actually, we haven't been able to find his number." Nick admitted. "Brass hasn't heard from him in over a year. I don't have his number. Hell, I don't even know where he is. Maybe Peru?" He sighed as he tried to decide if he should tell her but knew it would come out soon. "He... well, we haven't heard from him in a while but it looks like he and Sara were having some issues. He, uh, well he... it looks like... Damnit. I found divorce papers in her desk. He sent them a few weeks ago. She hasn't signed them, just filed them away in her desk." He could hear Catherine gasp, and heard a crashing noise and a few muttered curses. "Cath, are you there? Are you ok?"

"Did you say divorce papers?!" Catherine was nearly yelling. "No way, he wouldn't." She insisted, her head reeling, as she leaned down to clean up the mess from the toppled lamp and nightstand she had somehow managed to tip over. "What the hell happened?!" Her voice was a mix of shock, anger and confusion.

"I don't know." Nick said quietly. "Sara had been a bit down lately, wasn't her usual self. Actually, I guess looking back she was acting a lot like she had when things were bad between her and Grissom years ago. We just thought she was missing him." He shook his head, wondering now how he had missed the signs. "I'm scared, Cath." He admitted. "There's, uh... she was taking sleeping pills. That's not like her. And she... she has a bunch of paperwork here that she's signed declaring she doesn't want any medical intervention if she gets sick." A tear managed to escape and he was struggling to continue talking. "How did I miss this?" He whispered.

"It's not your fault." Catherine was emphatic. "Look Nick, here's what's going to happen. I'm packing now, I'll be on my way there within an hour. Grissom's lawyer will probably know how to get in touch with him, get me a name and I'll talk to them. If you're done at Sara's, lock up and go to the hospital. Be there with her." She spoke calmly and firmly, having switched into work mode. "But whatever you do, do not give the hospital those papers. We have no way to prove she did or didn't write them or sign them. It's too unlike her. And if she did, then she wasn't in her right mind, and we don't want them to withhold medical treatment before we can get a lawyer to fight them." Nick nodded despite the fact she couldn't see him.

"You're right." He agreed, but quietly knowing in his heart that she had written and signed them herself. He silently wiped at the few tears that had trailed down his face. "Thanks Cath. Let me know when you'll get in. I'll send you the lawyer's info and let you get in touch with Grissom."

"Nick? She's going to be ok. Sara's a fighter. She's tough." She reassured him. "But I need to go. I need to get to the airport." After hanging up, she swore. "Gil, I am going to kick your ass" she huffed. While talking to Nick she had pulled out an overnight bag and started packing. Dialing another number, she made plans to get back to Vegas as fast as possible.

Greg arrived at the hospital moments after Nick, finding Brass in a quiet corner of the waiting area attached to the Emergency Department, slouched in a chair and updating Nick on her condition.

"What happened? Where is she?" Greg asked frantically, his agitation evident. Were it any other situation, Nick or Brass would have done a double take to see him dressed so formally. He had obviously been somewhere nice - but the second he got the call from DB he had apologised to his date, paid for their meal, and rushed to the hospital.

"She was late for shift tonight. When we couldn't get ahold of her, DB sent me to pick her up. I just thought she was asleep, had missed her alarm." Nick explained for what felt like the hundredth time already, replaying it over in his mind as he explained to Greg that she just wouldn't wake up, so he called for an ambulance. At that point, Brass took over as Greg began to pace impatiently in front of them.

"They're running a bunch of tests. A CT scan didn't show any sign of a head injury. They didn't find any injuries. Said she was underweight, and her electrolytes weren't right. She's on IV fluids to try to balance it out again. There's a cardiologist and a neurologist in with her now. They're running her blood. More tests." He spoke slowly, feeling older than his years. "Last I heard, no one knew what was wrong."

Greg tried to make sense of what he was hearing as he paced and fidgeted with his hands. He, like Nick, questioned why he hadn't said something when he noticed she was starting to look unwell. It had crept up on her slowly - first her smile had vanished, and her laughter was less frequent. She started to decline invitations to go out, not wanting to see a movie or catch up for drinks. She had lost weight and her colour had paled. Occasionally he tried to make a joke with her, or offer her the good coffee and a favourite pastry to eat, but he had noticed she was just picking at her food. He couldn't recall the last time he actually saw her eat a full meal.

"Shit" he muttered under his breath, and then a realisation dawned on him. "Grissom!" he exclaimed, but before he could ask both Brass and Nick shook their heads.

"Do you know his number?" Nick asked. "We haven't been able to find it." Greg paused for a moment.

"No, but I think Hodges said he was still emailing him?" He said. "I'll call him now."

"Hodges."

"Hey Hodges, it's Greg. Are you still in touch with Grissom? Or do you know how we could get ahold of him?" he asked, listening as Hodges went on a long tangent. "No, we can't ask Sara." Nick and Brass watched as Greg continued to pace anxiously, nodding occasionally but clearly getting frustrated. "Look, I know you're busy. Please, I just need to get ahold of Grissom." Greg stomped and nearly threw the phone at the wall as he hung up. "I've got an email address. But Hodges said he hasn't actually heard back from him in at least six months."

"It's better than nothing" Brass said. "You two figure out what to say."
